detailed description

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with aspects of the invention as detailed in the appended claims.

In the related art, the network side periodically sends a system message (SI) to the user equipment to maintain synchronization with the user equipment. The system message includes synchronization information, which is used to indicate the location of the configuration information (also referred to as key system information) of the cell, so that the user equipment acquires the configuration information and completes the cell random access. The user equipment camps on the current cell for a long time and will receive system messages multiple times. If the configuration information of the cell is updated, the network side sends a change system message to the user equipment, and the location where the system message includes the updated configuration information is changed. It can be seen that there are system messages and system message changes in the related art. Both types of messages occupy network resources, and the user equipment needs to parse two kinds of messages.

In order to solve the above problem, in the embodiment, when the configuration information is not updated, the original system message is used, and the positions of the primary synchronization signal and the secondary synchronization signal are the initially specified positions of the system. When the configuration information is updated, the system message is still used, but the location of the primary synchronization signal and the secondary synchronization signal in the system message are sequentially exchanged to notify the user equipment.

FIG. 1 is a flowchart of a method for transmitting a system message according to an exemplary embodiment, where a method for transmitting a system message is used for a network side, where a network side is a base station or the like. As shown in FIG. 1, the method includes the following steps 101-104.

In step 101, first configuration information of the current cell is obtained.

In step 102, it is determined whether the first configuration information is consistent with the second configuration information indicated by the last system message.

In step 103, when the first configuration information is inconsistent with the second configuration information, a system message is generated, in which the positions of the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) are sequentially interchanged.

In step 104, a system message is sent to the user equipment.

This embodiment is implemented by the network side, and may be a base station (NB) or an evolved base station (eNB).

The network side may periodically acquire the first configuration information of the current cell, and determine whether the first configuration information is updated compared to the second configuration information when the system message was last sent. If no update occurs, a system message is generated, and the positions of the primary synchronization signal and the secondary synchronization signal in the system message are in the first position order. For example, the position of the secondary sync signal is first and the position of the master sync signal is at the back.

If it is the updated configuration information, a system message is generated, and the positions of the primary synchronization signal and the secondary synchronization signal in the system message are sequentially exchanged, that is, the second position sequence is adopted. For example, the position of the secondary sync signal is after, and the position of the master sync signal is first. At this time, the first configuration information indicated by the primary synchronization signal and the secondary synchronization signal is the updated configuration information. The system message has two functions. One is to indicate the updated configuration information, and the other is to notify the user that the device configuration information has been updated, and the user equipment needs to be updated synchronously.

The user equipment is idle in the current cell, periodically receives system messages, and keeps synchronization with the network side by using system messages. And acquiring configuration information of the cell at a specified location of the broadcast channel according to the system message. When there is a service demand, the user equipment needs to access the cell and switch to the active state. At this time, the user equipment sends a cell random access request to the network side according to the obtained configuration information.

In this embodiment, the system message is not changed, and the system message is adopted regardless of whether the configuration information is updated, which reduces the message type and saves network resources. System messages are reused by changing the structure of the system messages. Moreover, the update notification of the configuration information is realized by the sequential exchange of the position of the primary synchronization signal and the secondary synchronization signal, and the implementation is simple, and the burden on the network side and the user side is reduced.

This embodiment is applicable to a time division multiplexing system (TDD) and a frequency division multiplexing system (FDD).

In one embodiment, the positions of the primary synchronization signal and the secondary synchronization signal are sequentially interchanged, including: Orthogonal Frequency Division Multiplexing (OFDM) symbol position sequential interchange, or phase position sequence interchange during modulation.

As shown in FIG. 2, initially, the position of the primary synchronization signal is the position of the third OFDM symbol of subframe 1 and subframe 6. The position of the secondary synchronization signal is the position of the last OFDM symbol of subframe 0 and subframe 5. The secondary sync signal is in the front and the master sync signal is in the back.

If the configuration information is updated, the positions of the primary synchronization signal and the secondary synchronization signal are sequentially exchanged, and the secondary synchronization signal is followed by the primary synchronization signal. As shown in FIG. 3, the position of the primary synchronization signal is the position of the last OFDM symbol of subframe 0 and subframe 5. The position of the secondary synchronization signal is the position of the third OFDM symbol of subframe 1 and subframe 6. Of course, positional interchange can achieve positional order interchange.

Alternatively, when the primary synchronization signal and the secondary synchronization signal are modulated onto the frequency domain, the phase modulation parameter values of the two are interchanged. For example, initially, the phase modulation parameter value of the secondary synchronization signal is 1 and the phase modulation parameter value of the primary synchronization signal is 3. When the configuration information is updated, the phase modulation parameter value of the primary synchronization signal is 1, and the phase modulation parameter value of the secondary synchronization signal is 3. The change in the phase modulation parameter value causes the phase modulation positions of the primary synchronization signal and the secondary synchronization signal to be sequentially interchanged.

This embodiment provides a plurality of implementations of positional sequence interchange, which are applicable to various application scenarios, and are sequential exchange of positions between the primary synchronization signal and the secondary synchronization signal, have no influence on other information blocks, and have good compatibility.

For example, the initially specified position is as shown in FIG. 2, and the positions of the primary synchronization signal and the secondary synchronization signal in the transmitted system message 1 are as shown in FIG. 2. The configuration information is updated, the positions of the primary synchronization signal and the secondary synchronization signal are sequentially exchanged, and the positions of the primary synchronization signal and the secondary synchronization signal in the transmitted system message 2 are as shown in FIG. 3. The configuration information remains unchanged, and the locations of the primary synchronization signal and the secondary synchronization signal in the transmitted system message 3 are as shown in FIG.

The user equipment compares the position sequence of the primary synchronization signal and the secondary synchronization signal in the current system message with the position sequence in the last system message to determine whether the configuration information is updated.

For another example, the initially specified position is as shown in FIG. 2, and the positions of the primary synchronization signal and the secondary synchronization signal in the transmitted system message 1 are as shown in FIG. 2. The configuration information is updated, the positions of the primary synchronization signal and the secondary synchronization signal are sequentially exchanged, and the positions of the primary synchronization signal and the secondary synchronization signal in the transmitted system message 2 are as shown in FIG. 3. The configuration information remains unchanged, and the positions of the primary synchronization signal and the secondary synchronization signal are restored to the initially specified positions, and the positions of the primary synchronization signal and the secondary synchronization signal in the transmitted system message 3 are as shown in FIG. 2.

The user equipment compares the position sequence of the primary synchronization signal and the secondary synchronization signal in the current system message with the initially specified position sequence to determine whether the configuration information is updated.

In one embodiment, the method further comprises: step A1.

In step A1, it is determined whether a system message has been sent to the user equipment;

The step 102 includes: step A2.

In step A2, when the system message is once sent to the user equipment, it is determined that the first configuration information is compared to the previous Whether the second configuration information of the current cell is updated when the user equipment sends the system message.

In this embodiment, the user equipment has received a system message when it stays in the cell for a certain period of time (such as a few minutes). Alternatively, the user equipment switches from cell 1 to cell 2 and then to cell 1. When the cell 1 is camped for the first time, a system message is received.

The network side records the time when the user equipment moves to the current cell, and compares the time with the time when the system message was last sent to determine whether the user equipment has received the system message. The network side matches the configuration information obtained this time with the configuration information indicated by the previous system message to determine whether the configuration information is updated.

When the system message is sent to the user equipment, it is determined whether the first configuration information is updated compared to the second configuration information of the current cell when the system message was sent to the user equipment. When the first configuration information is inconsistent with the second configuration information, a system message is generated, in which the positions of the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) are sequentially interchanged.

In this embodiment, when the first configuration information is consistent with the second configuration information, it is compatible with the initially specified system message, or is compatible with the last system message. The system message is sent to the user equipment, so that the user equipment accesses the cell.

The implementation process of the network side transmission system message is described in detail below through an embodiment.

FIG. 4 is a flowchart of a method for transmitting a system message according to an exemplary embodiment, where a method for transmitting a system message is used for a network side, where a network side is an access network device such as a base station. As shown in FIG. 4, the method includes the following steps 401-406.

In step 401, the latest first configuration information of the current cell is obtained.

In step 402, it is determined whether a system message has been sent to the user equipment; when the system message has not been sent to the user equipment, step 405 is continued. When the system message was ever sent to the user equipment, step 403 is continued.

In step 403, it is determined whether the first configuration information is updated compared to the second configuration information of the current cell when the system message was sent to the user equipment. When the first configuration information is the updated configuration information, proceed to step 404. When the first configuration information is not updated, step 405 is continued.

In step 404, a system message is generated in which the positions of the primary synchronization signal and the secondary synchronization signal are sequentially interchanged.

In step 405, a system message is generated in which the positions of the primary synchronization signal and the secondary synchronization signal remain at an initial position.

In step 406, a system message is sent to the user equipment.

The user equipment can initiate random access according to the indication of the system message, and the network side receives the cell random access request sent by the user equipment, so that the user equipment completes the cell random access.

The two determining processes of step 402 and step 403 can be interchanged in position order. It is enough to satisfy two judgment conditions.

The above describes the implementation process on the network side, and the structure of the system message is improved. Correspondingly, the corresponding analysis of the user equipment system information. The following describes the implementation process of the user equipment.

FIG. 5 is a flowchart of a method for transmitting a system message according to an exemplary embodiment, where a method for transmitting a system message is used for a user equipment, where the user equipment may be a mobile phone, a computer, a digital broadcast terminal, and a messaging device. Equipment, game consoles, tablet devices, medical equipment, fitness equipment, personal digital assistants, etc. As shown in FIG. 5, the method includes the following steps 501 - 504.

In step 501, a system message sent by the network side is received.

In step 502, the system message is parsed to determine a first position sequence of the primary synchronization signal and the secondary synchronization signal.

In step 503, the first position order is compared with an existing second position order; wherein the first position order and the second position order are interchanged positions.

In step 504, when the first location order is inconsistent with the second location order, the configuration information of the current cell is acquired.

In this embodiment, the user equipment does not know whether the configuration information is updated, and does not know whether the position sequence of the primary synchronization signal and the secondary synchronization signal in the system message changes. When the user equipment moves to the current cell to receive the system message for the first time, it searches for the primary synchronization signal in the system message, and then searches for the secondary synchronization signal forward and backward with the primary synchronization signal as the center, thereby determining the primary synchronization signal and the secondary synchronization. The second position sequence of the signal. When the system message is received again, the first position sequence of the primary synchronization signal and the secondary synchronization signal in the system message is determined again. Comparing the first position order with the existing second position order. When the first position order is inconsistent with the second position order, it is determined that the configuration information is updated, and the configuration information of the current cell is acquired. Obtaining the location of the configuration information of the current cell according to the parsed primary synchronization signal and the secondary synchronization signal. And listening to the Physical Broadcast Channel (PBCH) to receive broadcast messages and obtain configuration information. When there is a service requirement, cell access and state activation are completed according to the obtained configuration information.

In this embodiment, the user equipment does not need to receive and parse the change system message, which reduces the message type and saves network resources. The purpose of notifying the user equipment configuration information update is achieved by changing the structure of the synchronization block in the system message. Moreover, the user equipment parses the primary synchronization signal in the system message to determine whether the configuration information is updated, and does not need to parse the complete system message, thereby reducing the processing load of the device.

When the OFDM symbol position order is used for interchange, the user equipment first parses the primary synchronization signal in the system message according to the initial specified position of the primary synchronization signal, and takes the third OFDM of subframe 1 and subframe 6 as an example in FIG. 2 The position of the symbol performs the main synchronization signal analysis. If the resolution is successful, it is determined that the configuration information is not updated. If the parsing fails, it is determined that the configuration information has been updated. The primary synchronization signal is parsed for the positions of the last OFDM symbols of subframe 0 and subframe 5. If the parsing is successful, it is determined that the configuration information is updated, and if the parsing fails, it is determined that the system message has an error.

For example, when the phase positions at the time of modulation are sequentially interchanged, the user equipment first demodulates the main synchronization signal in accordance with the initially specified phase modulation parameter value 3. If the demodulation is successful, it is determined that the configuration information is not updated. If the demodulation fails, it is determined The information has been updated. The main synchronizing signal is demodulated according to the phase modulation parameter value 1. If the demodulation is successful, it is determined that the configuration information has been updated. If the demodulation fails, it is determined that an error has occurred in the system message.

For example, the second position sequence is the position order of the primary synchronization signal and the secondary synchronization signal in the last system message.

When the user equipment moves to the current cell, when the system message is received for the first time (that is, when the system message 1 is received), the primary synchronization signal is searched in the system message 1, and then the primary synchronization signal is used as the center, and the secondary synchronization is searched forward and backward. The signal, in turn, determines the position order 1 of the primary sync signal and the secondary sync signal. Upon receiving the system message 2, the primary synchronization signal and the secondary synchronization signal in the system message 2 are parsed according to the position sequence 1. If the analysis is successful, it is determined that the configuration information has not been updated; if the analysis fails, the primary synchronization is performed in the position sequence 1. The positions of the signal and the secondary synchronization signal are sequentially exchanged to obtain the position sequence 2, and then the primary synchronization signal and the secondary synchronization signal in the system message 2 are parsed according to the position sequence 2. If the analysis is successful, it is determined that the configuration information is updated.

If the primary synchronization signal and the secondary synchronization signal in the system message 2 are parsed according to the position sequence 2, and the resolution is successful, when the system message 3 is received, the primary synchronization signal and the secondary synchronization signal in the system message 3 are preferentially parsed according to the position sequence 2. . That is, the positional order of the primary synchronization signal and the secondary synchronization signal in the last system message is preferentially analyzed. Of course, it is also possible to search for the secondary synchronization signal forward and backward with the primary synchronization signal as the center in the initial reception of the system message, and then determine the position sequence of the primary synchronization signal and the secondary synchronization signal.

For another example, the second position sequence is the position order of the initially specified primary synchronization signal and the secondary synchronization signal.

If the primary synchronization signal and the secondary synchronization signal in the system message 2 are parsed according to the position sequence 2, and the resolution is successful, when the system message 3 is received, the primary synchronization signal and the secondary synchronization signal in the system message 3 are preferentially parsed according to the position sequence 1. . That is, the positional order of the initial predetermined primary synchronization signal and the secondary synchronization signal is preferentially analyzed. Of course, it is also possible to search for the secondary synchronization signal forward and backward with the primary synchronization signal as the center in the initial reception of the system message, and then determine the position sequence of the primary synchronization signal and the secondary synchronization signal.

In an embodiment, the method further includes: step B1

In step B1, when the first location order is consistent with the second location order, the parsing of the system message ends.

In this embodiment, when the first location order and the second location are in the same order, the configuration information that has been obtained before may be used, without completing the parsing of the system message, and without listening to the PBCH. The processing load of the user equipment is reduced.

In one embodiment, the method further comprises: step C1 - step C2.

In step C1, when the primary synchronization signal in the system message is successfully parsed according to the initial location, it is determined whether the system message has been received by the current cell.

In step C2, when the system message is received by the current cell, the system message is parsed.

In this embodiment, when the configuration information is not updated, and the non-first time cell random access is initiated, the configuration information that has been obtained may be used, without completing the parsing of the system message or listening to the PBCH. The processing load of the user equipment is reduced.

The process will be described in detail below by way of examples.

Equipment, game consoles, tablet devices, medical equipment, fitness equipment, personal digital assistants, etc. As shown in FIG. 5, the method includes the following steps 601-606.

In step 601, a system message sent by the network side is received.

In step 602, the primary synchronization signal in the system message is parsed according to the initial location.

In step 603, when the primary synchronization signal in the system message fails to be parsed according to the initial location, the primary synchronization signal and the secondary synchronization signal in the system message are parsed according to the interchange location.

In step 604, the configuration information of the current cell is obtained according to the parsed primary synchronization signal and the secondary synchronization signal.

In step 605, when the primary synchronization signal in the system message is successfully parsed according to the initial location, it is determined whether the system message has been received by the current cell.

In step 606, the system message is terminated when the system message is received by the current cell.

When there is a service requirement, the user equipment sends a cell random access request to the network side through the current cell according to the obtained configuration information.
